RIM kicked off BlackBerry World 2011 in Orlando today, and the company wasted no time in revealing two new handsets — the Bold 9900 and 9930, complete with the shined-up BlackBerry OS 7. At 10.5mm thick, they’re the thinnest BlackBerry handsets to date and they’re also the first to come with the re-badged operating system (which was slated to be version 6.1 early on).

Both the 9900 and 9930 feature 1.2 GHz processors and 768MB of memory, 2.8″ capacitive touch screens at 640 x 480 pixels and 287 DPI, 8GB of internal storage, NFC support, and a 5MP camera with 720P video recording capabilities. The 9900 is HSPA+ and quad-band GSM while the 9930 is ready to rock on CDMA networks, and both feature the trademark BlackBerry QWERTY keyboard.

As for the BlackBerry OS, one of the key additions in version 7 is a much-improved Web browser. In addition to supporting HTML5 technologies (including the <video> tag), there’s a fast, new JavaScript JIT compiler under the hood which provides a big boost to modern Web apps. RIM has also added OS-wide voice-activated search capabilities and Wikitude-powered augmented reality out-of-the-box.

For those of you who pull double duty with your BlackBerry, OS 7 should make your system administrators extremely happy. The new BlackBerry Balance feature allows devices to distinguish between personal and office data. Balance also offers rich policy controls and the ability for admins to prevent corporate communications from being forwarded to non-work contacts, as well as the option wipe only corporate data from devices — meaning those of you who decide to pick up one of the hot new BlackBerry phones on your own could avoid having to carry two handsets around, one of which is no doubt a sluggish, outdated Curve running OS 4.5 if you’re in the same boat I am.
